WebCalendar contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the export_handler.php script not properly sanitizing user-supplied input to the 'id', 'format', 'use_all_dates', 'include_layers', 'fromyear', 'frommonth', 'fromday', 'endyear', 'endmonth', 'endday', 'modyear', 'modmonth' and 'modday' variables. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
